The council says the crossing needs to reopen for vehicles, buses and emergency services after years of disruption.
The bridge has been closed to motor traffic since 2019, but the closure has been putting pressure on other routes including Putney Bridge.
Albert Bridge is also now closed.
The call from Wandsworth follows Hammersmith & Fulham’s recommendation that available funding should focus only on keeping the bridge open for pedestrians, cyclists and river traffic, rather than delivering the full restoration needed for vehicles, buses and emergency services across south-west London.
Wandsworth Council says a London-wide solution is needed to restore connections across the capital.
Councillor Morritt, said: “This is a moment for leadership, not managed decline. After seven years of disruption, the time has come to transfer responsibility for Hammersmith Bridge to the Mayor of London, with the powers and funding needed to get this strategic crossing properly restored.
“Residents in Putney, Roehampton and across Wandsworth cannot be left with a half-baked plan that keeps Hammersmith Bridge permanently out of reach for buses, emergency vehicles and ordinary traffic.
“This bridge is not a local inconvenience. It is a strategic river crossing. Its closure has shifted traffic onto Putney Bridge and surrounding roads, made journeys harder for residents and businesses, and damaged public transport resilience across south London.
“Wandsworth will continue to champion the full reopening of Hammersmith Bridge. We are calling on the Government to use the current devolution agenda to put responsibility where it belongs: with London’s Mayor, working with Transport for London and the boroughs to deliver a serious, funded plan that restores proper connectivity for residents, buses and emergency services.”
We’ve contacted the Mayor’s office for comment.
